Studson SHK-1 Full Brim Vented Dual Cert Helmet

The Studson SHK-1 Full Brim Vented Dual Cert is built for job sites that require both US and Canadian compliance. Carrying dual SEI-certified credentials — ANSI/ISEA Z89.1-2014 (R2019) Type II Class C and CSA Z94.1-15 Type II Class C — this safety helmet meets the specific impact requirements of both standards in a single helmet. One SKU. Two markets. No compromises on protection. The interior is purpose-built for CSA compliance, featuring a Koroyd®-dominant construction that covers the full inner shell. Ionic+ pad sets at the top, front brow, and rear dial add comfort and moisture management where it counts most. The result is a helmet that protects from all angles while staying wearable across a full shift.

• Koroyd® Interior Construction: Features a welded tube, open-cell structure that crumples instantly on impact to absorb maximum force (meeting CSA Z94.1-15 Type II requirements for direct and angled impacts) while allowing consistent airflow for breathability.

• Ionic+ Comfort Pad System: Moisture-wicking, antimicrobial pads located at the top, front brow, and rear dial to keep the wearer comfortable during long shifts in hot environments.

• Twiceme® NFC Technology: An embedded, worker-preloaded NFC chip that gives first responders instant access to emergency contacts and medical info using any NFC-compatible device—no app required for responders.

• Fidlock® Magnetic 4-Point Chinstrap: A glove-friendly magnetic closure system with a 4-point configuration that ensures the helmet stays positioned correctly. Quick to fasten and easy to release.

• Perfect Fit System: A set-and-forget front and rear dial adjustment system that accommodates head sizes ranging from 53 to 63 cm.
